Oregon Alimony & Spousal
Support Calculator

Oregon relies on judicial discretion rather than a fixed formula to determine spousal support awards. Under Or.

Rev. Stat.

§ 107.105, courts evaluate a range of statutory factors to decide whether alimony is appropriate, how much should be paid, and for how long. This approach gives Oregon courts flexibility to tailor awards to each couple's unique divorce circumstances.

Because Oregon does not use a formula, alimony outcomes can vary significantly from case to case and from judge to judge. Courts in Oregon consider factors including duration of marriage, age, health, earning capacity, training needed, financial needs, tax consequences, contributions to education of the other.

The requesting spouse bears the burden of demonstrating a need for spousal support, while the paying spouse's ability to pay is equally important in the court's analysis.

Our Oregon alimony calculator and spousal support estimator above provides a preliminary estimate based on typical factor weighting in Oregon. Family law attorneys in Portland and across Oregon who know the tendencies of local judges can significantly influence the outcome — the same set of facts often produces different results in different counties.

Oregon recognizes several types of spousal support: temporary (transitional), compensatory, maintenance (long-term). Each serves a different purpose and applies under different divorce circumstances.

The type of alimony awarded depends on the length of the marriage, the financial circumstances of both spouses, and the specific needs demonstrated by the requesting party.

Temporary alimony (also called pendente lite spousal support) is awarded during the divorce proceedings to maintain the financial status quo while the case is pending. This type of support ensures that the lower-earning spouse can cover living expenses — including housing, utilities, and basic needs — until Oregon courts issue a final spousal support order.

Temporary support automatically terminates when the final divorce decree is entered.

Without a statutory spousal support formula, Oregon courts determine alimony on a case-by-case basis. Judges evaluate multiple factors including duration of marriage, age, health, earning capacity, training needed, financial needs, tax consequences, contributions to education of the other.

No single factor is determinative — the court weighs all relevant considerations together when calculating spousal support.

The requesting spouse must first demonstrate a genuine need for support. The court then evaluates whether the paying spouse has the ability to pay.

Even if need is established, alimony will not be awarded if the paying spouse lacks sufficient income or resources after meeting their own reasonable needs. Oregon courts aim to balance need against ability to pay while promoting eventual self-sufficiency where possible.

Because outcomes depend heavily on judicial discretion, the specific judge assigned to your divorce case can influence the result. Our Oregon spousal support calculator above provides a starting estimate, but family law attorneys familiar with local Oregon courts can provide valuable insight into likely outcomes and help present financial evidence in the most effective way.

Detailed financial documentation — including tax returns, pay stubs, monthly gross income worksheets, and career expert testimony — is critical for spousal support calculations.

Oregon's spousal support framework under Or. Rev.

Stat. § 107.105(1)(d) recognizes three legally distinct types, each with different purposes and duration expectations.

Transitional support is short-term and designed to help a spouse reenter the workforce through education or training. It typically lasts 1–5 years depending on the marriage length and the recipient's retraining needs.

Compensatory support reimburses a spouse for specific contributions to the other spouse's career, education, or earning capacity during the marriage — for example, supporting a partner through medical school or law school. The duration is tied to the period of contribution and the expected benefit to the recipient spouse.

Maintenance support is Oregon's long-term spousal support type, available when the economic partnership of the marriage resulted in ongoing financial dependency that cannot be reasonably overcome through retraining. It is most common in marriages of 15+ years where one spouse has been out of the workforce for an extended period, or in marriages where a health condition limits earning potential.

Oregon courts in Multnomah County (Portland) set maintenance duration based on when the receiving spouse can reasonably achieve economic self-sufficiency, rather than tying it to a fixed percentage of the marriage length.

The length of the marriage is the single most important factor in determining how long alimony lasts in Oregon. Short-term marriages (generally under 10 years) rarely result in long-term alimony awards.

When spousal support is granted for a short marriage, it is typically rehabilitative and limited to 2–5 years — enough time for the receiving spouse to become self-supporting through education or training.

For moderate-length marriages (10–20 years), spousal support duration in Oregon is often set as a percentage of the marriage length. As a general benchmark used by many courts, that figure falls in the range of **30–50%** of the marriage — though Oregon judges have discretion to award more or less based on the specific facts.

A 15-year marriage, for example, might result in a alimony award lasting 5–7 years. The specific duration depends on factors like the age of the receiving spouse, their earning capacity, and whether they sacrificed career opportunities during the marriage.

Long-term marriages (20+ years) may qualify for indefinite or permanent spousal support in Oregon, particularly when the receiving spouse is older, has limited earning capacity, or made significant career sacrifices to support the family. Even permanent alimony is subject to review and modification if circumstances change substantially — for example, if the paying spouse retires or the receiving spouse begins cohabiting with a new partner.

Under the Tax Cuts and Jobs Act (TCJA) of 2017, alimony payments pursuant to divorce agreements executed after December 31, 2018 are no longer tax-deductible for the paying spouse or taxable income for the receiving spouse. This was a major change from prior law, where the payor could deduct spousal support payments and the recipient reported them as gross income.

If your divorce was finalized before 2019 and you have not modified the agreement, the old tax rules may still apply to your payments. See IRS Publication 504 (Divorced or Separated Individuals) for the federal tax treatment that applies regardless of state.

Spousal support orders in Oregon can be modified if either spouse demonstrates a material change in circumstances. Common grounds for modification include significant changes in income (job loss, disability, retirement, or substantial raise), changes in the receiving spouse's financial needs, or the receiving spouse becoming self-supporting sooner than expected.

The party seeking modification bears the burden of proving the changed circumstances to Oregon courts.

Spousal support in Oregon typically terminates automatically upon the remarriage of the receiving spouse or the death of either party. Oregon also allows termination or reduction of alimony if the receiving spouse enters into a supportive cohabitation arrangement — essentially living with a new partner in a marriage-like relationship.

Consult a family law attorney if any of these circumstances apply to your situation.

In Oregon, child support and alimony are calculated separately but interact with each other. Most Oregon courts calculate child support first using the state's child support guidelines — use the Oregon Child Support Estimator to see how that figure is determined — then determine spousal support based on the remaining gross income available to each spouse.

This sequencing matters because child support obligations reduce the paying spouse's available income for alimony purposes. Some states impose a combined cap, limiting total support payments (child support plus spousal support) to a percentage of the payor's gross income, often **40–50%**.

Unlike child support, which follows formulaic guidelines tied to income changes, alimony modification generally requires a more substantial showing of changed circumstances. Child support generally takes priority in Oregon — if the paying spouse's income drops, courts typically preserve child support obligations before adjusting spousal support obligations.

Child support also ends when the child reaches the age of majority, which may trigger a review of alimony if the paying spouse's financial picture changes significantly during the divorce process.

Alimony is one component of the overall divorce financial picture. The Oregon Divorce Cost Estimator projects total attorney fees and filing costs for your case.

For divorces with children, the Oregon Child Support Estimator calculates guideline support amounts using Oregon's income model. And for marital property allocation, the Oregon Property Division Calculator covers Oregon's equitable distribution or community property rules.
